Heats of mixing at 30 °C and vapor pressures at 30, 40, and 50 °C have been measured for the system water–sulfolane. The excess thermodynamic functions ΔGE, ΔHM, and ΔSE have been calculated. The value of the heat of solution [Formula: see text] indicates that the sulfone group is a weak proton acceptor. The effects of water activity on the H− acidity function values in hydroxide media have been compared for the systems water–sulfolane and water–dimethylsulfoxide.

In the heat «cooling» investigated the temperature dependence of the specific heat capacity and thermodynamic functions doped strontium alloy AK1М2 in the range 298,15—900 K. Mathematical models are obtained that describe the change in these properties of alloys in the temperature range 298.15—900 K, as well as on the concentration of the doping component. It was found that with increasing temperature, specific heat capacity, enthalpy and entropy alloys increase, and the concentration up to 0.5 wt.% of the alloying element decreases. Gibbs energy values have an inverse relationship, i.e., temperature — decreases the content of alloying component — is up to 0.5 wt.% growing.

Enthalpy And Entropy

The solubility of Butylated hydroxyl toluene in aqueous and alcohol solutions were determined at different temperatures (293.15 to 313.15) K. Using Van’t Hoff and Gibb’s equations, some thermodynamic functions such as Gibbs energy, enthalpy and entropy of dissolution, and of mixing of Butylated hydroxyl toluene in aqueous and alcohol solutions, were evaluated from solubility data. The solubility was greater in butanol and minimum in water. The enthalpies, entropy and Gibb’s energy of dissolution were positive for all solvents.

An investigation has been made of the equilibria of hydration in the system solid lithium iodide-water vapour in the temperature interval covering the range of existence of the solid hydrates, using a dynamic method in a flow apparatus. From measured equilibrium pressures, the changes of the thermodynamic functions accompanying these reactions were determined and the values of the heats of formation, of the Gibbs energies of formation and of the absolute entropies of the solid mono-, di- and trihydrate of lithium iodide at 298.15 K were calculated.
